HOG HOLDERS Filed April 12, 19-54 INVENTOR WILLIAM H. DOOLEY ATTORNEYUnited States Patent HOG HOLDERS William H. Dooley, Perry, Mo., assignorto H. C. Reynolds, Perry, Mo.

Application April 12, 1954, Serial No. 422,570 4 Claims. Cl. 119-153 Myinvention relates to hog holders and holders for any kind of animal andby means of which ananimal may be caught and held for the purpose ofvaccination or other treatment.

An object of my invention is to provide an improved type of holderwherein the disadvantages of other holders likely to fail has beenavoided. More particularly to provide a noose-type of holder that willnot jam in its operation.

Other and further objects of my invention will appear from thespecification to follow and from an examination of the accompanyingdrawings, in which: Fig. 1 shows in section the complete hog holder,Fig. 2 shows an enlarged view of the locking mechanism in greaterdetail, Fig. 3 shows an enlarged sectional end view in perspective ofthe pivot block along lines 3-3 of Fig. 1 and Fig. 4 shows the pivotblock and end-plate in greater detail.

My present invention is an improvement in the conventional type of hogholder now finding wide use by farmers and veterinarians and whichconsists as shown in Fig. 1, of an elongated metal tube 1, having an endplate 5 secured to the lower end thereof, which end plate 5 has pivotedon one side thereof a cable securing pivot-block 4. End plate 5 andpivot-block 4 constitute the two parts of a hinge. A metal draw-rod 2extends into tube 1, one end of draw-rod 2 having handle 2a, the otherend of the draw-rod having one end of a cable 3 attached thereto and theother end of said cable being secured in the pivot-block 4. In catchingand holding an animal the draw-rod 2 is pulled outward from the tubethereby reducing the size of the noose in cable 3 which noose wouldnormally encircle a part of the animal.

Some of the older types of hog holders consist merely of a draw-rod 2working within a metal tube 1, the end of the cable being secured bywelding or otherwise to the tube 1, however the improved types ofholders make use of a hinge or pivot for securing the end of the cableand thus avoiding breakage of the cable occasioned by frequent andsevere bending at that point. The improved type of holders now findingwide use also make use of a catch, an improvement on which isrepresented by the reference numeral 6 in Fig. 1 showing my inventionand which will be described in more detail later. Heretofore in the art,when one desires to secure the end of the cable in the pivot block 4, ithas been by drilling a hole in the pivot-block 4 and securing the end ofthe cable in the hole by means of sweating in with solder, this beingnecessary due to the fact that welding the cable to the pivot-blockwill, because of the heat involved, remove all of the strength of thecable at this point.

It has been found that the use of a round draw-rod permits the cable tobe twisted and many times this takes place just at the time the holderis ready to be used. In the excitement that usually accompanies thecatching and holding of animals the user can not always pay attention tothe precise manner in which he might grasp and pull on the draw-rod toavoid twisting of the cable at the "ice noose. I have avoided thistwisting by making use of a rod having a cross-section other than round,reference numeral 2 in Fig. 2 showing it to be square. Means are thenprovided to prevent the rod from turning within the tube and it is shownin Fig. 2 how this may be accomplished by means of a guide shapedsimilar to the crosssection of the rod, the guide shown being a squarehole in extension 6a of locking mechanism 6.

In the usual type of holder finding wide use the end of the cable 3 isswetted into the pivot-block 4 as previously mentioned. I find thatinstead of entering the pivotblock 4 at the end thereof, it ispreferable to enter the pivot-block 4 with the end of the cable on oneside of the pivot-block 4 rather than at the end. In so doing it ispossible for the terminated end of the cable to line up exactly with theopen end of the metal tube 2while if the end of the cable is secured tothe end of the pivotblock 4 instead, there will be a sharp bend of thecable when it is completely drawn all the way into the tube, and thisbend will occur at the weakest part of the cable, namely where it joinsthe pivot-block 4. I also find it desirable to allow the end of thecable to rotate within the pivot-block 4 and this is shown moreparticularly in Fig. 3. Here it will be observed that the pivot-block 4is shown in section, the section line being at the securing hole. Thehole is slightly larger than the size of the cable being used and axialmovement of the cable through the hole is restricted by stops 10 and 11shown as washers which have been swetted on the cable at the placeswhere the cable emerges from the pivot-block 4. These stops 10 and 11constitute a bearing for cable 3 on both sides of pivot-block 4.

Cable 3 is usually made of highly resilient or tempered strands of wirewhich are twisted tightly. The cable will normally seek to return to thesame position it was in before it was flexed, the flexing in our casebeing when the noose is lightened or loosened. It is important to permitthis normal movement of the cable 3 to avoid kinks and twists in thecable, particularly at the noose portion.

We will now examine the catch or locking mechanism 6 in more detail.Fig. 2 shows a piece of flat metal which is bent at an angle greaterthan degrees constituting an extension 6a. It will be observed thatextension 6a has a square hole through which the square crosssectionedrod 2 passes. The size of this hole in extension 6a is made larger thanthe width of rod 2 so that when the plane of extension 6a isperpendicular to the axis of rod 2 the rod will slide easily through thehole. It will be observed that the main elongated portion of the flatmetal piece has a hole 7a through the same and through which a pin 7extends. Pin 7 is fastened to tube 1 and serves as a pivot into whichthe elongated piece is secured from appreciable movement in anyparticular direction although the elongated piece is free to rock up anddown. The hole in extension 6a is small enough to prevent the assembly 8from separating from pin 7. It is clear that side movement orappreciable rotation around the axis of pin 7 is prevented because thedraw-rod 2 can only move to the inside surfaces of tube 1.

Fig. 4 shows a preferred way to secure the end-plate 5 and pivot-block 4in pivotal relation. The pivot-block 4 is normally provided with a hole4:: extending on either side in one direction into which the bearing inend-plate 5 takes place. In a plane perpendicular to that of hole 4a Iprovide another hole 9 into which the end of the cable is secured.End-plate 5 has two lips shown as 5a and 5b shown as open in Fig. 4 andin closed position in Fig. l. Lips 5a and 5b are pressed into hole 4aand constitute in the assembled device a satisfactory pivot. Hole 50 isfor mounting the end-plate 5 on the tube 1.
